DeWalt DC411 Guide D'utilisation page 7

The operator can control torque reaction or kickback forces,
if proper precautions are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in the area where power tool
will move if kickback occurs. Kickback will propel the tool
in direction opposite to the wheel's movement at the point of
snagging.
d) Use special care when working corners, sharp edges etc.
Avoid bouncing and snagging the accessory. Corners,
sharp edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss
of control.
Safety Warnings Specifi c for Grinding
and Abrasive Cutting-Off Operations
Operations
a) Use only wheel types that are recommended for your
power tool and the specific guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b) The guard must be securely attached to the power tool
and positioned for maximum safety, so the least amount
of wheel is exposed towards the operator. The guard
helps to protect operator from broken wheel fragments and
accidental contact with wheel.
c) Wheels must be used only for recommended applications.
For example: do not grind with the side of cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding,
side forces applied to these wheels may cause them to
shatter.
d) Always use undamaged wheel flanges that are of correct
size and shape for your selected wheel. Proper wheel
flanges support the wheel thus reducing the possibility of
wheel breakage. Flanges for cut-off wheels may be different
from grinding wheel flanges.
e) Do not use worn down wheels from larger power tools.
Wheel intended for larger power tool is not suitable for the
higher speed of a smaller tool and may burst.
Additional Safety Warnings Specifi c for
Abrasive Cutting-Off Operation
a) Do not "jam" the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth
of cut. Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind the
rotating wheel. When the wheel, at the point of operation,
is moving away from your body, the possible kickback may
propel the spinning wheel and the power tool directly at
you.
c) When wheel is binding or when interrupting a cut for
any reason, switch off the power tool and hold the power
tool motionless until the wheel comes to a complete
stop. Never attempt to remove the cut-off wheel from the
cut while the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to eliminate the
cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let
the wheel reach full speed and carefully reenter the cut.
The wheel may bind, walk up or kickback if the power tool is
restarted in the workpiece.
